Our mailman was not closing the door to our mailbox all the way. When it rains the mail gets wet. I have called and complained. I went in , waited thru the service line and complained. Yet our mailbox (and that of several neighbors) is almost always left partially open. When it rains the mail gets wet. What lousy service. The mail carrier should push the mail all the way to the back AND --- CLOSE THE DAMN DOOR--- ALL THEY WAY! It doesn't rain here often so this should be an easy seasonal respectful action ALL mail carriers should exercise. I will be going in (again) on my next day off to see if I can actually talk to the Postmaster General of this branch.


My weekly advertising information from local businesses is not delivered every couple of months. Either the mail distributor or the postman doesn't properly do the job. I continue to complain.


I sure wish this branch would tell their postal deliverers to CLOSE THE MAILBOX COMPLETELY when it rains.
Our postal deliverer never seems to be able to close our mailbox all the way.
I even left a message (with mailbox flag up) asking them to close the mailbox completely during rainy periods.
I HATE getting wet mail.
It's also too bad they don't have an email address to register complaints... or even compliments.
